Which "behaviour"?

I'm honestly confused. As far as I can tell, everything is working as 
designed here.

The code tries to open an IPv6 socket, the kernel tries to load the 
module, SELinux denies and logs this. Each of these items is by design. 
Which are you suggesting should change?

Is it the audit log that is annoying people? If so, the SELinux policy 
should be a dontaudit.

Can we agree that unbound-anchor should not be reading sysctls to change 
it's behaviour?
